I am selling my used L100x2. It is in perfect working and physical condition with the exception of a nick on one of the side plates. Like all the Lunar amplifiers, it has a small footprint and is seriously under rated. I am am sure that it puts out over 2x150 @ 4 and 600x1 @ 4. It has factory installed 106 Hz high-pass and 88 Hz low-pass crossover chips. The modules can be altered to control the crossover from 48 Hz low pass up to 7960 Hz high pass with installation of various resistor values.
